WINDOW-SCREEN.

To all whom it may concern:

Be it known that I, ALEXANDER D. WALKER, a citizen of the United Statesof America, and a resident of the city of Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in lVindow-Screens, of which the following is aspecification.

My invention resides in the provision of a construction of the abovetype which can be readily installed and, which when in its positions ofuse and non-use will serve to exclude rain or other fo-reign substancesfrom the screen receiving chamber.

A further object is to provide a simple and comparatively inexpensiveconstruction which can be secured against movement from the receivingchamber, the same when so positioned serving to effectively close themouth of the latter.

Other objects will be set forth as my description progresses and thosefeatures on which I desire protection, succinctly deinved in my annexedclaims.

Referring to the accompanying drawing wherein like numerals of referenceindicate like parts throughout: Figure 1 is a fragmentary perspective ofthe window frame and lower sash equipped with my invention. Fig. 2 is avertical section thereof illustrating the sash as partly raised, and thescreen secured in its posit-ion of non-use and provided with suitablepacking, and Fig. 3 is a horizontal section on small scale taken on line3 3 of Fig. 2.

For the purpose of illustration I have shown my invention applied to thelower sash, as 1, which operates in a window frame 2, of any well knownor suitable construction, for supporting the sash for sliding verticallytherein. Window frame 2 is provided in its sill 3 with an opening 4,forming the mouth of an underlying chamber 5, for the screen 6, the saidmouth extending into communication with the slideways 7 provided for thesash.

The frame of screen 6 is formed of bars grooved to provide seatingportions for the wire fabric, as shown, and in carrying out myinvention, I provide the upper of these bars with an angular extension 8which projects outwardly to have bearing on the window sill when thesash is in closed position. In providing this bar of the screen and saidextension 8, a blank of sheet metal is bent to provide substantiallyU-shaped angularly Specification of Letters Patent.

disposed parts, connected at the adjacent longitudinal edge portions oft-he open sides, and fitted in respective rabbets 9, formed in the underand inner side faces of the lower rail of sash 1.

The lower or under wall of extension 8 is relatively short and this hasits free edge portion bent upwardly to engage the companion wall andthereby serve to maintain a proper spacing between the two and insure ofthe said lower extension wall having snug engagement with sill 3 whenthe sash is closed. Further, by this construction, said short wallprovides a retaining means for suitable packing, as 10, (see Fig. 2),arranged for engagement with the sill forltovardly of the mouth 4E ofthe screen cham- Reference numeral 11 indicates outwardly flaredopenings formed in the top bar of screen 6, these openings beingprovided in pairs, the component openings of these pairs being formed inrespective walls of said top bar and registering, whereby a securingmeans 12, in the form of wood screws can be seated therein forengagement with either the sash or the window sill, in which latterinstance it is engaged directly with the stop 14.

Extension 8 can, of course, be provided with packing 10 at all times,butthis safe guard is particularly desired when the sash can be elevated oropened to a position from over the screen, as will be readilyunderstood.

In practice, storage of screen 6 is effected by first disengaging screws12 fromsash 1, then, if packing 10 has not been previously provided,inserting a strip of suitable flexible material between the walls ofextension 8, the lower or shorter of these walls being bent down topermit of this, after which the screen is lowered into chamber 5 untileXtension bears on sill 3. Screws 12 are` then passed through theopenings 11 from the opposite side of the screen so as to engagein stop14.- of the window sill..

Various changes can be made in the minor details of construction, asfall within the scope of my annexed claims. Further, I wish itunderstood that, if desired, both upper and lower sash of a window canbe provided with screens, connected therewith, in accordance with myinvention, for movement to and from their operative positions.

Having thus fully described my inven- :ytionf'what' Iielaim as new anddesire to se- 'cure by Letters Patent of the United States,

1. In apparatus of the character described, a frame having a sashslidably supported therein and being formed in one end section With aslot, ,a screen extending through the slot of said frame, one end railof said sash being formed in one end face and one side face Withrabbets, one bar of the frame of said screen being seated in one rabbetof said sash, an angular extension on said bar seated in the otherrabbet of said sash, said extension being substantially U- shape andhaving one of its Wall portions arranged for engagement with said framewhen the sash is closed, and means removably securing said screen tosaid sash.

2. In apparatus of the character described, a Window frame provided onits sill With a stop, a sash slidably supported in said frame forengagement With said stop and formed in the lower and inner faces of itsbottom rail with communicating rabbets, said sill being formed With aslot arranged in proximity to and parallel With the said stop thereof,.a screen projecting through the slot of said sill and having its topbar seated in one rabbet of said sash, said top bar being formed Withopenings for securing means, said openings iiaring toward each side ofthe screen, securing means engaged in the openings of said top baradapted to be engaged With either said sash or said stop of the Window'frame sill, and an extension on said top bar of the screen having adownturned portion arranged to engage said Window frame sill outwardlyof the slot thereof to guard the latter against ingress of foreignsubstances.
